l'tUOF AND METHOD OF LAYING.

Application filed. July 141, 1923. Serial No. 651.477.

This invention relates to roots and method of laying, and provides a construction whereby a copper or other suitable metallic surfaced roof may be produced by merely overlying roofing units with the desired metal in thin sheet form, the metal being unattached to the base units over any considerable extent so that its expansion and contraction, due to heat changes, may take place unhindered by the different rate of expansion and contraction or the underlyin material whereby curling or warping of the roof material is prevented while retaining the strength and solidity derived from the base units.

For a more complete understanding of this invention reference may be had to the accompanying drawings in which:

Figure l-represents in perspective a piece of base material herein shown as a strip shingle,

Figure 2 is a similiar view of the sheet metal strip for overlying the strip shingles.

Figure 3 is a section on the line 38 of Figure 2 showing the manner in which the lower edge of the metalic strip is bent.

Figure 4 is a fragmentary perspective of the finished root.

Figure 5 is a section on line 5-5 of Figure 4r.

By way of example this invention has been illustrated in connection with strip shingles such as are now commonly made by saturatingt rag felt with asphaltic or bituminous material and surfacing them with grits such as crushed slate and cutting LEA them into strips, each strip having along one edge shingle-simulating tabs formed by inwardly extending cut outs 3, it being cornimon in the art to lorm'such strips insections each containing four shingle-simulating tabs as illustrated in Figure 1. For the purposes of this invention a stri of copper, or other suitable metal in thin s set form shown at 5 in Figure 2, is formed into general roofing element form with the cut out portions 6 mating the cut outs 3 in the strip shingle, but prelerahi of greater depth so that when the metal is str1p is superposed on the strip shingle as laid, as shown in Figures 4 and 5, the lower ends thereof extending beyond the ends of the shingle-simulating tabs. The upper edge oi the metallic strip may terminate short of the upper edge of the'shingle strip, it bein only necessary to cover the portions of t e shingle strip ordinarily enposed to the weather, but preferably the metallic strip extending sufliciently above the upper ends of the cut outs to form portions through which nails 7 may be driven to attach the metallic strips, and if desired the shingle strips also on the roof. The lower ends of the metallic strip tabs are then bent in under the ends of the tabs of the shingle strip as shown at 8. i

The metallic strip may be in lengths similar to the shingle strips, or of different lengths, as may be desired, and they may be laid after each course of shingle strips have been laid and the lower ends then turned in under the shingle-simulating tabs. or the two may be made fast to the roof together as may be found more convenient.

While as shown the base material over which the metal is laid is strip shingles, it is evident that individual shingles could be treated in the same manner, as well as roll material, or any other form, it being only essential that the metal shall overlie the bases of the shingle material ordinarily exposed to the weather, being preferably formed to engage beneath the lower edges of the base units in order to prevent detachment of the metal therefrom. :It will be noted, however, that the stri s are not attached to the base material as y cement or otherwise so that they are free to expand and contract with heat changes entirely independently of the base material, to which they are held only by the nails for fastening the metallic strips in position. A; metallic surfaced roof is thus provided in which only very thin sheet metal is necessary since a substantialbacking of roofing units of non-metallic material is provided.

Having thus described an embodiment of this invention it should be evident to those skilled in the art that various changes may be made therein without departing from its spirit or scope-as defined by the appended claims.

I claim:

till

Eli

1. The method of laying a roof which comprises laying a course of non-metallic roofing elements, overlaying at least the portions of said elements exposed to. the weather with thin sheet metal, turning the lower edge of the metal up under the exposed butt ends of said elements, fastening the metal in position, superposing in lapping relation a course of non-metallic roofing units, and overlying said course oil nonmetallic roofing units in the same manner with thin sheet metal.

2. The method of laying a roof which comprises laying a course of non-metallic roofing elements, overlaying at least the porti ons of said elements exposed to the weather with thin sheet metal, turning the lower edge of the metal up under the exposed edges of said elements, and fastening the metal in position by fastenings extending 10 therethrough above the portion which is normally exposed to the weather after the roof has been laid.

In testimony whereof I have afiixed my signature.

FREDERICK C. OVERBURY.
